Laila · Answer 1

First, you would substitute z with 12 since z = 12.

12 : 3 - 5 (12) + 4 (12 - 2).

Then, you would follow the order of operations.

12 : 3 - 60 + 40

4 - 60 + 40

-56 + 40

-16

So your answer is - 16.

Kai Nolan · Answer 2

12 : 3 - 5 (12) + 4 (12 - 2)

= 4 - 60 + 4 (10)

= - 56 + 40

= - 16
